Jiangsu Haifa Machinery Manufacturing Co., Ltd.

2×2.8 Million Tons/Year Methanol Synthesis Plant  Shaanxi Coal Group Yulin Chemical is an ultra-large dual-series continuous chemical plant, typically involving synthesis gas purification, methanol synthesis loop, raw methanol condensation, distillation, process condensate, circulating water, and finished product delivery. Public technologies from Topsoe and Johnson Matthey both indicate that the core of a large-scale methanol plant lies in an efficient synthesis loop, reaction heat recovery, and long-term continuous operation. Therefore, process pumps must give priority consideration to high temperature, high pressure, methanol flammability and toxicity, NPSH, and mechanical seal reliability. Under the API 610 pump configuration, OH1 is suitable for process water, utility services, and general low-pressure liquids; OH2 centerline-supported pumps are suitable for crude methanol, refined methanol, column bottoms, and high-temperature process media; OH3 and OH4 used for compact vertical in-line installations; OH6 high-speed pumps are suitable low-flow, high-head injection and booster services. BB1 can be used for-flow circulating water; BB2 radially split pumps are suitable for high-temperature, continuous heavy-duty conditions; BB3 and BB4 multistage pumps are used for medium-to-high pressure process liquid boosting; BB5 double-casing multistage pumps (Barrel Pumps) are suitable for-pressure methanol feed, boiler feed water, and high-head product delivery. VS1 is suitable for large cooling water and underground sump services; VS4 and VS5 are suitable for, condensate, and vertical sump discharge; VS6 and VS7 Vertical Can Pumps are suitable for low NPSHa, easily vaporized methanol, tank output, and high-head liquid transfer. Jiangsu Haifa Machinery Manufacturing Co., Ltd. www.jslgpump.com has established a complete API 610 product system covering OH1–OH6, BB1–BB5, VS series process pumps, and can perform engineering selection for the 2×2.8 million tons/year methanol project based on Flow, Head, Vapor Pressure, NPS/NPSHr, API 682 Seal Plan, Material Selection, and Operating Range. According to publicly available information on its official website, the company has long provided high-temperature and high-pressure chemical pumps for demanding process plants in petrochemical and coal chemical industries.
